The witchweed Striga gesnerioides and the cultivated cowpea: A geographical and historical analysis of their West African distribution points to the prevalence of agro-ecological factors and the parasite’s multilocal evolution potential [PDF]

PLoS ONE, 2021
The increasing severity of Striga gesnerioides attacks on cowpea across West Africa has been related to its prolificity, seed mobility and longevity, and adaptation to aridity, in a context of agricultural intensification.

A potential role of heat‐moisture couplings in the range expansion of Striga asiatica [PDF]

Ecology and Evolution
Parasitic weeds in the genera Orobanche, Phelipanche (broomrapes) and Striga (witchweeds) have a devastating impact on food security across much of Africa, Asia and the Mediterranean Basin.

Novel Sources of Witchweed (Striga) Resistance from Wild Sorghum Accessions [PDF]

Frontiers in Plant Science, 2017
Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. Away from cultivated farmland, wild

Global Invasive Potential of 10 Parasitic Witchweeds and Related Orobanchaceae [PDF]

AMBIO: A Journal of the Human Environment, 2006
The plant family Orobanchaceae includes many parasitic weeds that are also impressive invaders and aggressive crop pests with several specialized features (e.g. microscopic seeds, parasitic habits).

Striga hermonthica: A highly destructive pathogen in maize production

Environmental Challenges, 2022
Maize is a major cereal crop in sub-Saharan Africa (SSA). Subsistence farmers mostly plant it in areas where the parasite Striga hermonthica's action often reduces the harvest.

Witchweed’s Suicidal Germination: Can Slenderleaf Help? [PDF]

Agronomy, 2020
The parasitic plant Striga hermonthica (Delile) Benth. is stimulated to germinate by biomolecules (strigolactones) produced in the roots of host and some non-host plants. Non-hosts induce Striga’s suicidal germination and are therefore used as trap crops. Among trap crops, the Slenderleaf legume in the genus Crotalaria (Crotalaria brevidens (L.) Benth.)

GWAS provides biological insights into mechanisms of the parasitic plant (Striga) resistance in sorghum

BMC Plant Biology, 2021
Background Sorghum yields in sub-Saharan Africa (SSA) are greatly reduced by parasitic plants of the genus Striga (witchweed). Vast global sorghum genetic diversity collections, as well as the availability of modern sequencing technologies, can be ...

Striga seed-germination activity of root exudates and compounds present in stems of Striga host and nonhost (trap crop) plants is reduced due to root colonization by arbuscular mycorrhizal fungi. [PDF]

, 2009
Root colonization by arbuscular mycorrhizal (AM) fungi reduces stimulation of seed germination of the plant parasite Striga (Orobanchaceae). This reduction can affect not only host plants for Striga, resulting in a lower parasite incidence, but also ...
